RESUMEN
INTRODUCTION: Idiopathic sudden hearing loss (SHL) is a relatively frequent entity in the adult population with unk nown cause in most cases. There are few studies in pediatric age and its diagnosis and management are a challenge for health professionals. OBJECTIVE: To relate macrolide therapy as a causal agent of sudden hearing loss in pediatric patients. CLINICAL CASE: 3-year-old girl with no relevant pathological history, with normal neonatal hearing screening and age-appropriate language development. She consulted due to an upper airway infectious process, treated on an outpatient basis with azithromycin for 3 days. One week later, she developed bilateral hearing loss, confirmed with Brainstem Auditory Evoked Potentials (BAEP), and started treatment with oral methylprednisolone and intratympanic corticosteroids. During treatment, imaging, laboratory, and genetic studies were performed, ruling out other causes of SHL, so the recent use of macrolides was considered as a possible diagnosis. As no clinical improvement was observed 6 weeks after the treatment, confirmed by the absence of response in the steady-state auditory evoked potentials and BAEP, simultaneous bilateral cochlear implant surgery was carried out. Four years after surgery, the patient showed good speech-language develop ment and adequate school performance. CONCLUSIONS: Ototoxicity is a cause that must be considered in the case of SHL in childhood. A multidisciplinary approach will allow effective treatment in these patients, in which early management with an adequate hearing aid will restore hearing and achieve adequate speech development and linguistic competence.
